what do the colours of the French flag represent.

                                                           THE FLAG

The French flag contains three vertical stripes of equal width. From the flagstaff to the end, these colors are blue, white, and red. More than 20 countries use these three colors in their flag, including the United States, the United Kingdom, and Australia.
                                     HISTORY
Encyclopædia Britannica notes the meaning of the flag's colors are deeply rooted in the country's aristocratic and revolutionary history. Traditional colors of the flag in pre-revolutionary France contained a white background with a blue shield and the gold Fleur-de-lis depicting the royal coat of arms. However, after the French Revolution, the country's leaders wanted a simpler design that supported the new values of the nation, and the French Tricolour was adopted.
